ABSTRACT:
A warning light assembly is provided that includes a simple drive train for accomplishing an 180.degree. or more oscillation of a light beam. By advantageously utilizing a speed-reduction mechanism, a transmission for converting rotary motion to oscillating motion and a coupling for multiplying the angle of oscillation, the drive provides an inexpensive and rugged enabling design the warning light assembly to oscillate a light beam through angles heretofore unattainable.
